Description

Application

Reactant for:
• Hydrothermal preparation of thorium uranium silicate (Th1-xUxSiO4) uranothorite solid solutions
• Fabrication of dense NaA zeolite coatings
• Reactant for preparation of tungsten modified silica as catalyst for liquid phase oxidation of styrene

Sodium metasilicate (SMS) has been used in the preparation of polypyrrole/sodium metasilicate (PPy/Na2SiO3) and polythiophene/sodium metasilicate (PT/Na2SiO3) composites, novel high dielectric constant materials for use in power electronic systems.

SMS can also be used:
• To prepare NaZnSiO3OH, a novel chiral framework material which has potential application in ion exchange, adsorption and catalysis.
• As a low-cost alternative to tetraethyl orthosilicate (TEOS) to synthesize highly ordered mesoporous silicas.
• To prepare geopolymer concrete.
